A Polymer80 pistol is by far the easiest 80% gun to finish. In this post, we will show you what tools we used in our PF940SC completion video and when we used them. This is an old post and I have restored it due to popular demand. There has been a lot of changes in how to build a Polymer80 since April of 2019 when I first posted this.

I would suggest you check out the classes from my good buddy Marine Gun Builder over at Freedom Crew University. He has taken Polymer80 building to new heights. And we absolutely don’t do the build with drill presses any more. Back in the day, Polymer80 used to send a mill bit and this was the origional method of completeion.
